COMBGNAT / BCI PLATE 01

01 / 03 · Mount

Put sound in front of a fruit fly.

A physical Drosophila stands inside a flat visual arena. A head electrode carries its modeled response to the bench.

FRUIT-FLY BRAIN–MACHINE INTERFACE / LOCAL DEMO

Let a fruit fly assemble the next playlist.

Local audio becomes a visual field. A recognizable Drosophila samples it through a reduced hex-retina model. Its spikes choose one next track—on this device, without pretending the fly can read.

Choose an audio field

Choose a field, then let the fly sample its energy. A DNp09-like burst commits one next clip locally.

THE FLY OPERATES THE INTERFACE

A body, a probe, and an explicit translation.

The specimen illustration is not a mascot floating beside a dashboard. Its compound eye receives the field; a visible head probe feeds a deliberately reduced browser model; named motor-like outputs move the sampler and commit the queue.

  1. 01

    See

    Audio energy is arranged as time × frequency cells in front of the compound eye.

  2. 02

    Fire

    Twenty-four leaky integrate-and-fire units respond to sampled cell intensity.

  3. 03

    Walk

    DNa02 steers frequency; DNa01 advances time; MDN steps the eye backward.

  4. 04

    Commit

    A DNp09-like burst selects the closest remaining field and writes it locally.

03 / HONESTY PLATE

WHAT THIS BENCH IS—AND IS NOT

The fly is visible. The limits are, too.

REAL INPUT

Actual browser audio analysis

Bundled WAV clips and your local files are decoded in-browser. The spectrogram-like field comes from sample energy, not filenames.

REDUCED MODEL

24 units, clearly labeled

This interface does not run a whole fly brain. Published 2026 FlyEM counts—165,122 neurons and roughly 10.2M connections—are context, not runtime claims.

LOCAL OUTPUT

A playlist on this device

The selection rule is authored by people. The fly has no goal, taste, language, wallet, or claim to biological fidelity.

DEEP BOUNDARY

Chain write remains SOON

No contract, signature, mint, reward, or transaction occurs. You only meet that boundary after completing the local interaction.

PUBLIC MATERIALS

Twelve plates. One unmistakable instrumented fly.

DEEP FEATURE BOUNDARY

Chain write is SOON.

Your local playlist is preserved. Combgnat has no deployed contract and did not ask for a wallet, signature, or transaction.
